Tropical Summers

Planning a trip to the magnificent Whitsunday Islands over the summer holidays? December and January offer a true taste of the Tropical Queensland Summer.
We say taste because Hamilton Island is located in a subtropical climate zone. PERFECT! 

If you love warm weather, you’re in luck! December and January are the height of summer, characterised by high temperatures and significant humidity.
Here is some helpful hints:

  • Average Daytime Highs: Expect the mercury to hover around 30°C to 31°C 
  • Average Overnight Lows: Even nights are warm, sitting around 24°C to 25°C 
  • Humidity: This is the key factor. Humidity is high, often ranging from 50% to 80% = muggy.
  • Sea Temperature: The ocean is blissfully warm, averaging 28°C, making swimming and snorkelling irresistible.
  • December also marks the start of the wet season, which typically peaks in January and February. 
  • Rainfall: These months record the highest rainfall of the year. However, it’s essential to understand that rain in the tropics rarely means a whole day is a washout.
  • Tropical Showers: The most common pattern is hot, sunny mornings followed by short, heavy afternoon downpours or overnight rain. These tropical showers can be a refreshing cool-down.
  • Lush Scenery: The benefit of this rain is the landscape: the islands turn an incredible, vibrant green, and seasonal waterfalls, like those at Cedar Creek Falls on the mainland, start to flow magnificently.
  • Secret Waterfall Spots can also be found on Whitsunday Island the largest of the island in the Whitsunday group of 74. Finding a tour operator to take you there is a must.

Just pack your lightest clothes, hat and sun protection for your  adventure in the Whitsundays.
